ICE CRUSHER Filed July 5, 1939 Patented Aug. 27, 1940 UNITED STATESPATENT OFFICE ICE CRUSHER Application July 5, 1939, Serial No. 282,840

4 Claims.

My invention relates to ice crushers, and more particularly to a devicefor crushing ice into small fragments for use in icing drinks, juleps,and ice bags.

` One object of my invention is to provide a novel ice crusher adaptedto rapidly and easily crush ice into small fragments.

Another object of my invention is to provide a device for crushing icein which the fragment size may be controlled.

Other and further objects of my invention will appear from the followingdescription.

In the accompanying drawing which forms part of the instantspecification, and which is to be read in conjunction therewith, and inwhich like reference numerals are used to indicate like parts in thevarious views:

Fig. 1 is a side elevation of an ice Crusher showing one embodiment ofmy invention.

Fig. 2 is a plan view of the ice crusher shown in Fig. l1 with the coverremoved.

Fig. 3 is a front elevation of the ice Crusher shown in Fig. 1, withparts along the line 3-3 of Fig. 1 in section.

Fig. 4 is a sectional View taken along the line 4 4, Fig. 3.

Fig. 5 is a fragmentary view similar to Fig. 4

showing the rotary crushing element in position for forming the smallerice fragments. Referring now to the drawing, a base member I is formedwith a standard 2, and provided with a plurality of feet 3, which may beof rubber or the like. The standard supports a bowl 4 adapted to receivethe ice to be crushed. The lower end of the bowl 5 is formed as an openpassageway of rectangular cross-sectional shape. The passageway isprovided with a pluralitymf fins 6 along one side wall thereof, and aplurality of ns 'I along the opposite side Wall thereof. By reference toFig. 4 it will be noted that the fins 1 do not extend upwardly along theside Walls to as great a distance as the ns 6. The other two side wallsof the lower end of the bowl 5 are bored to receive bearings 8 and 9.Bearing 8 is formed at the end of a handle member I 0, to which a shaftII of octagonal crosssectional shape is rigidly secured. Bearing member9 is formed at the end of a nut I2 adapted to screw onto a threadedportion I3 formed at the end of the shaft I I.

The shaft I I is adapted to pass through an assembly of cutters,assembled upon a bushing I4 having a hexagonal cross-sectional shape.The assembly comprises cutting members I5 and spacer members I6. Each ofthe cutters I5 is of the shape shown in Figs. 4 and 5, and is p-rovidedwith a sharpened point I'I and a sharpened point I 8. The points I'I andI8 are located 180 apart, and point I I is located at a greater distancefrom the axis of the bushing I4 than the 5 point I8.

In assembling the cutters upon the bushing I4,

a number of arrangements may be employed. It will be observed that sincethe bushing I4 is hexagonal, adjacent cutters may be apart. A 10 handyassembly is as follows. A long point, another long point 60 behind, athird long point 60 behind, a short point in phase relation with theadjacent long point, and a short point 60 ahead. The diametricallyopposite cutters will then be arranged as follows. A short point.another short point 60 behind, a third short point 60 behind the secondshort point, a long point in phase relation with the short point, andl along point 60 ahead of the adjacent long point.

In the arrangement shown I have provided two sets of four ns 6 and 'Iand live cutters. The spacing is such that the cutters pass between thens.

Adjacent the openings for the bearings 8 and 25 9, I provide guide ns I9and 20, and centering fins 2|. 'Ihe fins I9, 20 and 2| are adapted toposition the cutter assembly opposite the openn ings in the side wallsso that the shaft II can be readily passed through the bushing I4.

Referring now to Fig. 4, it will be noted that the direction of rotationin order to crush ice will be in a clockwise direction, as viewed in thefigure. In other words, ice will be crushed upon the fins I by thecutters. When the fins 'I are 35 employed the crushed ice will becoarser in texture than when the cutters are reversed as shown in Fig.5. It will be observed in Fig. 5 that the direction of rotation will becounter-clockwise, and that fins 6 will be effective for coaction with40 the cutters. The ice in this case will be crushed to a finer degree.

Hinged to the standard 2 is a cover member 22 provided with downwardlyextending fins 23 and 24. The lower ends of the fins 23 and 24 45 areprovided with stepped portions 25. Ihe function of the projecting finsis to prevent the ice from moving upwardly during the rotation of thecutters.

In operation, if it is desired to crush ice 50 coarsely the assembly isas shown in Fig. 4 with the ns 1 effective to co-operate with the cutterassembly. Ice is dropped into the hopper and the cover 22 swung toclosed position and the cutter assembly rotated by means of handle 26,55

gio

which is secured to the handle arm I. The rotation of the cutterassembly will crush the ice between the iins 'I and the cutting points,and the crushed ice will drop downwardly by gravity through the opening21 into a receptacle which may be placed under the opening upon the basemember I. A pair of ns 28 are formed in the base member to act as stopsfor the receptacle enabling it to be positioned directly under theopening 27.

If it is desired to crush ice more finely, the nut I2 is unscrewed andthe shaft I I and handle assembly moved laterally out of the cutterbushing I4. The cutter assembly will then be supported by the ns I9, 2Gand 2I. The cutter assembly is lifted out of the hopper, reversed anddropped into the hopper. The fins i9 and 2i) will position the cutterassembly laterally in the hop per for registration with the bearingopenings in the hopper sides. The fins ZI will positionthe cutterassembly vertically for registration with the bearing openings in thehopper sides. rThe operating shaft I I may then be inserted through thebushing iii and the nut I2 again screwed onto the threads I3. Thedirection of rotation with the cutter reversed will, of course, beopposite.

It will be seen that I have accomplished the objects of my invention. Ihave provided a novel ice crusher assembly which is adapted toconveniently and expeditiously crush ice. My de vice will crush ice to aiine or coarse size as desired. The adjustment for change in the size ofice particles may be quickly and conveniently made. The fins 23 and 24upon the cover member prevent the ice from riding around in the bowl.

It will be understood that certain features and sub-combinations are ofutility and may be employed without reference to other features andsub-combinations. This is contemplated by and is within the scope of myclaims. It is further obvious that various changes may be made indetails within the scope of my claims, without departing from the spiritof my invention. It is, therefore, to be understood that my invention isnot to be limited to the specific details shown and described.

Having thus described my invention, I claim:
